Is it possible to develop a Plex Media Server service that auto-deletes just watched (over X%) media files and associated files bearing same name (subtitles, including subtitles with country code pre-extension ie. file.en.srt)?
This is the only reason why I still use XBMC and not fully Plex - I miss the After Watch plugin that removes watched media from my PC. I download through SickBeard and CouchPotato a huge stream of media, and my hard drive fills up pretty easily, so I love to be able to automate removal of unneeded content. This is sorely missing on Plex side right now.
While I don't need to delete the files, I second the vote for a configurable (at what % it triggers), and what to do (delete, trigger something else (maybe extendable, so you can auto-update trak.tv or something), etc.)
Auto archiving maybe, I don't think I'd personally use auto delete ever (pretty easy to add more space to my network). Recode to a user defined max quality setting after viewing. I tend to not rewatch content often, but I do like to keep it on hand just in case.
